Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538508, here are decompositions:

37 + 538471 = 538508
97 + 538411 = 538508
109 + 538399 = 538508
151 + 538357 = 538508
199 + 538309 = 538508
211 + 538297 = 538508
241 + 538267 = 538508
307 + 538201 = 538508

Showing the first eight; more decompositions exist.
